Of course, the young man did not suspect Mrs. Jarsell of being connected in any way with crime of any sort. Still it was strange that the perfume from Sumatra should form a link between her and Sir Charles Moon, with Penn intervening. It was also strange that Mrs. Pelgrin should hint that Mrs. Jarsell had secrets. She had not said as much in so many words, but the general trend of her cautious conversation went to show that Mrs. Jarsell was not entirely open and aboveboard. The landlady had wondered where the owner of the Grange got her money. Now why should she so wonder, unless she had proofs that the said money was not come by honestly? And why, also, should she, in a quite unnecessary way, mention her nephew, who was the Thawley station porter--friendly with Mrs. Jarsell to such an extent that there was a chance of his getting a legacy? Ladies of wealth do not make friends of railway porters without reason, and Dan wished to learn the reason in this particular case. By a diplomatic question he had ascertained from Mrs. Pelgrin that her nephew was the sole Sheepeak person employed at the station. Consequently he would naturally be the sole person who knew Mrs. Jarsell and all about her; therefore it was not impossible that the lady befriended the man so that he might not speak of her visits to town. Yet why should he not do so, should Mrs. Jarsell's doings be entirely honest? Then there were three motor cars, a quite unnecessary number for a lady to keep, especially as, according to her own story, she went out little and spent most of her time in attending to Miss Armour. On the whole, although his suspicions were vague, Dan had an idea that Mrs. Jarsell's doings would not bear the light of day. Still--and especially since she had procured him the biplane--he would not have troubled about her rustic affairs save for the fact of the perfume. It might be--and this he hoped to discover--that Penn's confession would show more plainly the link which connected Mrs. Jarsell with the Hampstead crime. Yet, on the face of it, the very idea seemed monstrous, and Dan scorned himself for his folly as he wrote the letter to Penn. Nevertheless, something stronger than himself drove him to post the letter.
